The motion determination apparatus includes a motion sensor for sensing motion of an electronic device and sending out a motion parameter. A processor receives the motion parameter to determine whether or not his motion is a meaningful motion. A device controller activates a device function according to the determination.

Motion determination apparatus and method thereof

The present invention provides an image processing apparatus capable of obtaining good shake-corrected images in electronic image stablization irrespective of changes of image-taking conditions. An image processing apparatus comprises a shake correcting part that performs coordinate transformation processing based on shake information to an input image that is generated by use of an image-pickup device, and a method changing part that changes a coordinate transformation method for the coordinate transformation processing.

Image processing apparatus, image-pickup apparatus, and image processing method

A method includes identifying a frame of a spherical video as a key frame, storing a compensation component based on position data of a camera in association with the key frame, and compensating for a movement of the camera in a subsequent frame of the spherical video based on the key frame and the compensation component associated with the key frame

Stabilization based on accelerometer data

A method and apparatus for smoothing an image in a plurality of video frames consisting of a current frame and at least one previous frame. The position of at least one pixel in each of the plurality of frames is determined to provide respective determined positions. An adjusted position of the at least one pixel in the current frame is calculated based on the determined positions.

Method and apparatus providing motion smoothing in a video stabilization system

Methods of processing a frame in a video sequence of digital images are described, the methods comprising: determining a global motion vector for the frame relative to a previous frame in the sequence; deriving a jitter function from the global motion vector, the jitter function comprising an estimate of undesired motion of the frame relative to the previous frame; determining whether the frame is blurred above a first predetermined threshold; and if so, stabilising the frame using the jitter function and applying a deblur function to the frame.

Video Stabilisation with Deblurring

A processing device (D) is dedicated to image frame stabilization of digital video sequences in an electronic equipment (El), such as a digital camera, for instance. This processing device (D) comprises processing means (PM) arranged, for each current image frame of a video sequence, for determining a type of motion present in the video sequence from global motion parameters of the current image frame and the ones of at least one preceding image frame of this video sequence. These parameters are determined from a motion estimation between the current image frame and the preceding one of the video sequence. The motion determination is followed by a selection of a jitter extraction technique amongst at least two jitter extraction techniques depending on this determined motion type. The jitter extraction technique thus chosen is used to determine a jitter intended to be removed from the determined global motion parameter(s) in order to remove unwanted motion(s) present into the current image frame.
